Be it known li, MARTIN L. DUNNAM, av citizen of the nited Sintes,residing at Meridian, in the eounty of Lauderdale end Stilte ofMississippi, lieve invented new and useful improvements in Combined Condensers and l'ieedlleter Heaters, of which 'the following is nspeoioetion.

Chis invention relates to improvements Yfeed Wai/er, and more combinedcondenser end -ifs invention to purify ilron'i solid sind el'ien'nen-l1mi'- pnrities and Witter .in o

lilihile the preferred :toi-ins of: this invenu 'tion nre illustratedupon the accompanying; sheet olib yet it is to be understood that inieiuinges rosy be nmde partiv A; from the scope thereof.

Fgnrel is e. View in vertical longitudinal section7 oit the combinedcondenser end feed water heater es contemplated in this invention. Fig'.f2 is :in enlarged View in trans `verse vertical section of thecondenser' und :feed Water heater es contemplated in this invention.

` The condenser end feed Wolter heater eoinprises e cylindrical easing lclosed et en'eli end, supported above n horizontal heating ehninberextending the entire length theren under and having o vertical flue orchimney 3 :it one end to supply heet to eporize the 4water in thecondenser. Aillusie heet from the boilers may be employed to supplylient to the elmniber or e. grate 4l may be provided at the end oppositethe ilnev 2. lt is preferable to provide en inner wall labout the upperportion of the easing; l leaving a small space therebetween. The pipe 6leiding.:1r from e source or water supply discharges into the space etthe bottom on one side and upon the other side on external feed pipe 7leads from the bottom or" this space into the interior of the easing lbelow the horizontal center line. The lower'end of the feed pipe 7 isprovided with a flootopereted valve 8 arranged to close the dischargeend of the feed pipe. By this eonstruction the water 'from thesource ofsupply is raised in temperature before being,` led into the Vaporizingportion of the condenser. A plurality of horizontal air pipes 9 arewronged in the opper portion of the easing l in. rows following thecontour oi the oor ingl es near :is possible. These pipes 9 nresupported in 'the end walls of the easing end ere open therethrough, sothat eooi sir will be. drown through by the draft up the flue Below eeehrow or' sir pipes 9 are er renged correspondingly euri/ed drip pieter'LILO supported from the end vilells-o the ing 1 to celeb the ldrip ofeondensetion whieh gethers upon the air pipes @rip platee l0 have theirlower side edges so ooi'istrueied es to leed 'bhe drip int-o horiaoi ilarranged diemetri-celly opposite il.. These troughs 1l ere preiferehlycurved on the radius of a circle having their enter sides tightlysecured against the inner Wells of the easing: l sind their inner sidesentend ing slightly beyond e seinieirele, so that 'the drip muy beCaught and retained by there. The bloat valve 8 is adjusted to retainthe Water level in the easing below 'the bottoni of ihe drip trough il.lhrough the front end or' the easing l pipes 12 leed from the bottoni ofthe drip trough and eoniieeted to a, pipe 13 leading to pump, which.loroes the condensed Water thrfmgh pipe to feed the boiler or batteriesof boilers,
